LJUNGSTRÖM® GAS-GAS HEATERS IN SELECTIVE CATALYTIC REDUCTION (SCR)

Our world-renowned Ljungström® Gas-Gas Heater can optimize tail-end SCR heat recovery application by raising the flue gas to the required SCR reaction temperature.

A Cleaner Operation

Our ability to match the selection of our advanced heating elements providing superior even flow distribution, together with optimized sootblowing equipment and procedures, ensures the GGH remains clean and efficient.

Specialized Sealing System

The optional unique multiple fan and duct sealing system is very different from that of the Ljungstrom® Air Preheater as it is specially designed to minimize direct radial leakage.

BUILT ON EXPERIENCE

The development of the Ljungstrom® Air Preheater into a SCR gas-gas heater platform was first achieved by LJUNGSTRÖM engineers in 1985, and we continue to be the world leaders in the design, manufacturing, installation, and maintenance of these systems.

The Ljungström® Gas-Gas Heater for a SCR platform has been installed in over 6 countries. We are the only manufacture, with a global footprint and this amount of experience! We are proud of the fact that we have supplied four of the world’s largest SCR GGHs!

Thanks to our decades of experience, and our commitment to ongoing research and development, our pioneering gas-gas heater has become the leading solution for SCR reheat applications around the world.
